Any fog gazers want to spell out what they see out there would be appreciated.
It's quite hard to do that without a save or a HD screenshot. I can distiniquish some tiles (for example 2W1S is a flood plain, 2N is a hill) but not all.

The hill 1SW of the warrior or the one 2N of the settler?
Looks accurate AFAICT, though I'm pretty sure the river continues between the PF? and PH? in the north.
I'm inclined to move the settler as well, as SIP doesn't look strong to me. I'd first sent the warrior 1NE, then depending on what is revealed, the settler either 2N or 1NW.

What are grassland mines?
You probably mean grassland hill mines.

2) We're going to have culture focus, for at least two cities. Which leaves me wandering whether we should aim for a third one as well.

Since this is an extremely complicated map/victory I would just settle right away and then go for a tight city formation, dropping the second city at (possibly near) the forest tile near the fish and using that city to build Moai Statues. The issue with this is obvious, the lack of gold makes a religion rush impractical. But perhaps we could simply rush an enemy and take the holy city? Regardless if we are going for a religion I think moving into the forest tiles is the only viable option to gain what seems to be river and forest-free tiles in the N-west.
I'm not sure but I think it's a plain hill 2 steps south west obviously surrounded by rivers. This would bring us an extra shield per turn which is of huge importance early on and create a tremendous defensive position vs barbarians and others. But it's a waste of 2 turns for something that could be something else! [...]

I'm not sure about that. In my experience in a culture win the first city will get there almost autonomously, the second aided by hermitage and some artists, but the third by a MASSIVE amount of artists. I think taking the step of the third legendary city might take up too many great people points that might be needed elsewhere... Also, the cultural and research paths usually don't mix, since culture victory means cranking up the culture slider at the expense of the research slider, and we need the research as well in this game...
It would be good if there is some fast-teching, easy-sharing AI in the game like Mansa, who can do a lot of the teching for us...
